Abstract Achieving rational control over chemical and energetic properties at the perovskite/electron transport layer (ETL) interface is crucial for realizing highly efficient and stable next‐generation inverted perovskite solar cells (PSCs). To address this, we developed multifunctional ferrocene (Fc)‐based interlayers engineered to exhibit adjustable passivating and electrochemical characteristics. These interlayers are designed to reduce non‐radiative recombination, and to modulate the work function (WF) and un…

Photovoltaic-powered batteries offer a promising integrated solution for sustainable energy in portable electronics, yet conventional designs face challenges in integration, miniaturization, and flexibility. We address this through a dual-functional, material-sharing strategy using ethyl viologen diiodide to achieve synergistic performance enhancement in photovoltaic-powered batteries. The ethyl viologen diiodide-modified perovskite solar cells exhibit 26.11% efficiency and retain 96.2% of their original performan…

<title>Abstract</title> Angstrom-scale polygonal rings in monolayer amorphous carbon (MAC) not only tailor its electronic and mechanical properties, but also endow the atomically thin membrane material with diverse angstrom pores for precise regulation of the subatomic species separation and transport, crucial for technological advances across various fields including catalysis, energy devices, and medical applications. However, the lack of industrial-scale synthesis route of intrinsic MAC has severely hindered th…

ABSTRACT Solution-processible fullerene derivatives have been extensively used as electron transport layers (ETLs) of inverted perovskite solar cells (PSCs); however, the commonly used 58π-electron [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) often tends to dimerize, especially under continuous illumination, severely compromising long-term stability. Herein, we develop a 1,4-unsymmetrical addition strategy and synthesize two novel 56π-electron fullerene derivatives bearing multiple bulky functional groups suc…
